ABSTRACT:
A method of optimizing write current in a data storage system. The write current is optimized by measuring a bit error rate in the storage system as a function of the write current in the presence of background interference stress and adjacent track interference stress. An optimum write current level is determined as a function of the measured bit error rate.
